Abstract
Regarding the price of meat product filling in comparison with the negligible cost of the collagen casings, whole roll of the casings is discharged only on suspicion of a small cut during handling. Once the casings are designed to be biologically resistant, they represent relatively problematic waste that is nowadays rather transported to landfills. This represents a significant cost; once the role is opened, it becomes extremely voluminous. The long-term study that was carried out on a commercial scale assessed two methods of utilization: composting of highly disintegrated casings and composting of charred casings. Robust qualitative and financial analysis revealed that the composting of charred casings was more meaningful both from agrochemical and financial point of view.
